Hi Paraview community members,

Here is a picture of the model I imported through an unstructured grid file shared in this dropbox [link](https://www.dropbox.com/s/jbd4fg0gs6y3zog/particles.vtk?dl=0).

As you can see that, the model looks very rough due to not enough particles.

I was wondering if there is a way, to generate more particles based on these current particles in Paraview to make this model look finer? Thank you!

All the best,  
Jie
